Heat and mass transfer from the mantle: heat flow and He-isotope constraints
heat flow helium isotope ratio geothermal energy mass transfer
2015/9/10
Terrestrial heat flow density, q, is inversely correlated with the age, t, of tectono-magmatic activity in the Earth's
crust (Polyak and Smirnov, 1966; etc.). «Heat flow-age dependence» ind...
East-west mantle geochemical hemispheres constrained from Independent Component Analysis of basalt isotopic compositions
mantle isotope domain basalt supercontinent
2017/4/11
In order to decipher the mantle geochemical heterogeneity that reflects material differentiation and circulation within
the Earth, we examined mid-ocean ridge basalts (MORB), ocean island basalts (OI...
Trace element and isotopic evidence for temporal changes of the mantle sources in the South Shetland Islands, Antarctica
trace elements Sr-Nd-Pb isotopes subduction component heterogeneous mantle South Shetland Islands
